Big Fish Aquarium

Terms of Use

These Terms of Use govern your access to and use of the Big Fish Aquarium website, online store, digital content and related services.

Last Updated: September 24, 2026

This website is operated by BIG TANK LLC doing business as Big Fish Aquarium (“Big Fish Aquarium,” “BFA,” “we,” “us,” or “our”). By accessing or using this website, placing an order, creating an account or otherwise using our online services, you agree to these Terms of Use.

1. Acceptance of These Terms

By accessing or using bigfishaquarium.com, you agree to comply with these Terms of Use and any policies incorporated into them by reference.

If you do not agree with these terms, you should not use the website or online store.

You must have legal capacity to enter into a binding agreement to make purchases through the website.

2. Website Use

Big Fish Aquarium provides this website for informational, ecommerce, customer-service and aquarium-service purposes.

You agree to use the website only for lawful purposes and in a manner that does not interfere with the operation, security or availability of the website or the rights of other users.

We may modify, suspend or discontinue any feature, product, service, page or portion of the website at any time.

3. Products, Livestock + Product Information

Big Fish Aquarium sells aquarium livestock, corals, invertebrates, plants, food, equipment, supplies and related products.

We make reasonable efforts to provide accurate product descriptions, photographs, specifications, care information, sizes and other product details.

Because livestock is living and naturally variable, appearance, size, coloration, markings, behavior and other characteristics may differ from photographs or descriptions unless a product is specifically identified as WYSIWYG or otherwise represented as the exact specimen being purchased.

Manufacturer packaging, specifications, ingredients and product appearance may also change without notice.

4. Inventory + Availability

Product and livestock inventory can change quickly. A product appearing on the website does not guarantee that the item will remain available until an order has been successfully processed.

Online and in-store inventory may be separate. An item available in the physical store may not be available for online purchase, and an online listing may not reflect current in-store availability.

Certain brands, products or inventory may be designated in-store only. This may include merchandise that Big Fish Aquarium chooses not to sell or ship through its ecommerce store.

We may cancel or modify an order if an item becomes unavailable, inventory information is incorrect or the order cannot reasonably be fulfilled.

5. Orders + Payments

By submitting an order, you represent that the information you provide is accurate and that you are authorized to use the payment method submitted.

Submission of an order does not guarantee acceptance. Big Fish Aquarium may refuse, limit or cancel an order for reasons including inventory availability, pricing errors, suspected fraud, payment issues, shipping limitations or other fulfillment concerns.

If we cancel an order after payment has been processed, the applicable amount will be refunded according to the payment method and processing procedures available to us.

6. Pricing, Promotions + Discounts

Prices, discounts, promotions, shipping offers and product availability are subject to change without notice.

Promotional offers may have specific start dates, expiration dates, product restrictions, purchase minimums or other eligibility requirements.

Some discounts apply automatically at checkout and may not appear as reduced product pricing on product or category pages.

Unless expressly stated otherwise, promotional offers and discount codes may not be combined.

We reserve the right to correct pricing or promotional errors and to cancel transactions affected by an obvious error.

7. Shipping, Delivery, Returns + Livestock Claims

Orders are subject to Big Fish Aquarium’s applicable shipping, logistics, return, refund and livestock-guarantee policies.

Live fish, corals, plants, frozen foods and dry goods may require different shipping methods, rates and fulfillment procedures.

Customers are responsible for providing complete and accurate shipping information and for reviewing applicable shipping requirements before ordering.

Dead-on-arrival, livestock-loss and similar claims must comply with the documentation, notification and eligibility requirements stated in the applicable livestock guarantee or shipping policy.

Carrier delays, weather conditions and circumstances outside Big Fish Aquarium’s reasonable control may affect shipment timing.

View our Shipping & Logistics Policy for additional information.

8. Membership Programs

Big Fish Aquarium may offer membership programs that include discounts, credits, special pricing, livestock updates, promotions or other benefits.

Membership benefits are subject to the terms applicable to the membership level and may change from time to time.

Membership benefits generally apply only while the membership is active and may be subject to exclusions, order minimums, eligible-product restrictions or other conditions.

Credits, discount codes or other membership benefits have no cash value unless expressly stated otherwise.

9. Aquarium Maintenance, Installation + Consultation

Information about aquarium maintenance, installation, consultations and related professional services may be provided through this website.

Specific service scope, scheduling, pricing, payment terms, cancellations, property access, warranties and other requirements may be governed by a separate estimate, invoice, agreement or service policy.

Where a separate written service agreement conflicts with these general website Terms of Use, the specific service agreement controls with respect to that service.

10. AI-Assisted Content + Technology

AI Transparency

Some content may be created or reviewed with AI-assisted tools.

Big Fish Aquarium may use artificial intelligence or other automated tools to assist with drafting, editing, organizing, researching or improving website content, product information, marketing materials, customer communications or internal business processes.

AI-assisted content is intended to support, not replace, human judgment. Big Fish Aquarium may review, edit or verify AI-assisted material before publication where appropriate.

Artificial intelligence systems can produce incomplete, outdated, inaccurate or misleading information. We do not represent that AI-assisted content is error-free.

Product availability, livestock compatibility, aquarium care, dosing, water chemistry, equipment requirements and similar decisions should be independently confirmed using current product instructions, manufacturer guidance and appropriate aquarium expertise.

AI-assisted content does not create a warranty, guarantee, professional-client relationship or promise of a particular aquarium outcome.

11. Aquarium Care Information

Care guides, compatibility information, aquarium recommendations, blog content, product descriptions and other educational material are provided for general informational purposes.

Aquarium conditions vary based on tank size, water chemistry, filtration, livestock, feeding, maintenance, source water, environmental conditions and many other factors.

Big Fish Aquarium does not guarantee that a particular fish, coral, plant, invertebrate, product, treatment, dosing method or aquarium-care approach will be appropriate for every system.

Customers are responsible for researching livestock and equipment requirements and making appropriate decisions for their own aquariums.

12. Intellectual Property

Unless otherwise indicated, the website and its original content, design, branding, photographs, graphics, text, product descriptions, logos and other materials are owned by or licensed to Big Fish Aquarium and are protected by applicable intellectual-property laws.

You may not submit material that is unlawful, misleading, defamatory, infringing, abusive, fraudulent or otherwise inappropriate.
